部件號：01-W3403F-03M、84-W8403F01E、01-W3403F-03J、84-W8403F01D、MVME2101-1
MVME2100 處理器模塊的配置涉及多個方面，以下是一些主要的配置內(nèi)容：
控制單元：MVME2100控制單元是整個CPU的指揮控制中心，負責協(xié)調(diào)整個電腦有序工作。它根據(jù)用戶預先編好的程序，依次從存儲器中取出各條指令，放在指令寄存器IR中，通過指令譯碼(分析)確定應該進行什么操作，然后通過操作控制器OC，按確定的時序，向相應的部件發(fā)出微操作控制信號。
運算單元：運算單元是運算器的核心，負責執(zhí)行各種算術(shù)和邏輯運算。
存儲單元：MVME2100存儲單元包括CPU片內(nèi)緩存和寄存器組，是CPU中暫時存放數(shù)據(jù)的地方。它保存著那些等待處理的數(shù)據(jù)或已經(jīng)處理過的數(shù)據(jù)。
在處理器模塊的配置過程中，還需要考慮以下參數(shù)設置：
MVME2100 模塊檢測完成時間：用于設定“模塊配置檢測完成”信號的回答時間。當超過該時間未收到完成信號時，視為實際硬件配置與配置不符。該時間設定單位為100ms，默認設定為650。
參數(shù)傳送到模塊的時間：用于設定CPU中的參數(shù)傳送到各模塊的最大允許時間。時間設定單位為100ms，默認設定為100。對于有PROFIBUS-DP主站接口的CPU，可以通過本次參數(shù)來檢測從站的啟動情況。
Emerson/MOTOROLA MVME2100 VME processor module
Settings:
? Processor: 200 MHz MPC8240
? Cache: 16 KB/16 KB
? SDRAM: 32 MB
? Flash memory: 5 MB
? Handle: Scanbe
Part number: 01-W3403F-03M, 84-W8403F01E, 01-W3403F-03J, 84-W8403F01D, MVME2101-1
The configuration of the MVME2100 processor module involves many aspects. The following are some main configuration contents:
Control unit: The MVME2100 control unit is the command and control center of the entire CPU, responsible for coordinating the orderly work of the entire computer. According to the user's pre-programmed program, it takes out each instruction from the memory in turn, puts it in the instruction register IR, determines what operation should be carried out through instruction decoding (analysis), and then sends a microoperation control signal to the corresponding component by operating the controller OC, according to the determined timing.
Arithmetic unit: Arithmetic unit is the core of the arithmetic unit, responsible for performing various arithmetic and logic operations.
Storage unit: The MVME2100 storage unit consists of the on-chip cache and register group of the CPU, which is the place where data is temporarily stored in the CPU. It holds data that is waiting to be processed or has already been processed.
During the configuration of the processor module, the following parameter Settings need to be considered:
MVME2100 Module test completion time: used to set the answer time of the "Module configuration test completion" signal. If the completion signal is not received within the specified time, the actual hardware configuration is inconsistent with the configuration. The time setting unit is 100ms, and the default is 650.
Parameter transfer to module: Used to set the maximum allowed time for parameters in the CPU to be transferred to each module. The time setting unit is 100ms. The default value is 100. For a CPU with a PROFIBUS-DP master interface, you can use this parameter to check the startup status of the slave.
